What happens when you need transmission repair?


It's a scary time when your transmission acts up. Most drivers don't know what to expect - they just know major transmission repair can be expensive. Many people fear that they will be taken advantage of by unscrupulous shops. That's why you need a shop you can trust.


When your car acts up, give us a call or come by. We will check your fluid and test drive your car for free. That will give us an idea of what your problem may be. We also have the latest computer scanners which help pinpoint the problem. Another diagnostic tool is pulling the pan off your transmission. Our certified professionals will examine your pan looking for metal shavings and other foreign material.


Many times the test drive is enough to let us know that your problem is minor. We pledge to do only the work you need to get you back on the road. Many times customers come in to our shop expecting a big repair bill, and we are able to send them on their way for under $100. 


Other times a major problem is indicated. When that happens, you still have service options. We will be glad to discuss your options and help you make the best choice.


Here are options for major repair: 


Custom rebuild: The transmission is removed and disassembled for a rebuilder to inspect, clean and replace worn and broken parts. We will then re-install your transmission. You will receive an estimate before any work is done, and the final price varies within that estimate depending on which parts need to be replaced.


Exchange: For customers who don't have time to wait for a custom rebuild, we offer exchanges for many transmissions. Our technicians have already rebuilt units, so they are ready to install in your car. Final price is known before the service is started.


Certified transmissions: Certified transmissions are factory-rebuilt units that can be installed in two-three days and include an 18-month guarantee. This is a good option if you're in a hurry for your car and would like a fixed price.


Factory exchange: If you prefer a warranty from your car's manufacturer, we can order a transmission that has been rebuilt at your manufacturer's facility. When we receive the transmission, we will install and test drive it and then send your removed transmission back to the factory. This option allows you to have a fixed price, and the manufacturer of your car guarantees the transmission. A factory-rebuilt transmission is generally a more expensive option.


Our work is guaranteed - nationwide.


You can feel comfortable having work done at our shop. We guarantee all of our transmission work through the Automatic Transmission Rebuilders Association (ATRA). Our warranties are honored at more than 2,000 ATRA shops throughout North America, so if you are out of town and have trouble, you are still covered.


When you pick up your repaired vehicle, you will receive a written warranty and instructions about how to get warranty service if it is needed, in Tyler or across North America. We're always glad to answer any questions you have about your vehicle's operation.
